Here’s why you can’t trust electric bike companies when it comes to battery range
It’s a tale as old as time. Man sees electric bike advertisement touting 50-mile range. Man buys e-bike. Man’s first ride gets 25 miles before the battery’s charge dwindles. Man is justifiably disappointed.
So what gives? Why does it seem like you can never trust the range numbers that the electric bike makers tell us?
The short answer is that it seems that way because that’s the way it is. You simply can’t trust the range figure printed on an electric bicycle’s marketing material. At least not most of the time.
There are several good reasons for this, so let’s break them down.
No standard for range testing for e-bikes
First of all, e-bikes aren’t like cars. There aren’t any standards for battery range testing on e-bikes. It’s not like the “EPA-rated 32 mpg” or “NEDC-tested 250 miles of range” you’ll see in car ads.
Range ratings for e-bikes aren’t determined by outside agencies. They are determined by the bike makers themselves. In the best case, the printed distance figures come from real-world range testing. Some companies like Aventon and Lectric eBikes have stepped up with real-world range data on their sites for each level of pedal assist or throttle riding. That’s the best case. But in the worst case, some companies just give us numbers that they pull out of a hat or theorize that their bike can probably achieve.
Which companies are which? Without hard data displayed on the company’s site, it’s hard to know. That’s the problem. Unless a company puts real-world testing data out there, we’re left to guess.
Range varies WIDELY based on a number of factors
This is actually the single largest reason that you almost never actually achieve the range quoted by the e-bike manufacturer. There is a huge variance in the real world battery range of an e-bike on a single charge. There are literally dozens of factors that have significant impacts on range.
Even if an e-bike company wanted to give one number as the ultimate, end all and be all, certified range of their e-bike – a number that they are confident you can achieve – they simply wouldn’t be able to do it. It just depends on too many factors.
It’s amazing how many factors can have a measurable impact on e-bike range.
Are your tires low on air or pumped to the max? Are you riding uphill or downhill? Tailwind or headwind? Brake rub? Crouched or sitting up tall? Is the road wet? Did you eat a big lunch? Have you eaten big lunches for the last 30 years? What gear are you in? What power level are you in? Knobby or smooth tires? Are you wearing a backpack or carrying cargo on a rack or basket? Any passengers with you? Are you riding on asphalt? Concrete? Dirt? Gravel? Sand? The list goes on and on.
Depending on the answers to those questions, the exact same electric bike could travel 15 miles or 60 miles on a single battery charge. Yeah, it’s wild.
Many people expect e-bike ranges to be more repeatable, similar to car mileage. But then again, consider that unlike cars, which often outweigh their drivers by 20 to 1, you probably outweigh your bike by 3 or 4 to 1. So changes in you or your environment have a much bigger impact on range than they do for other larger vehicles likes cars and trucks.
All of these factors make it harder for e-bike companies to offer a realistic range, and so they usually test for the best-case scenario. That means a lightweight rider (often listed at 150 lb., even though the average American adult female and male each weigh 170 and 200 lb., respectively) riding on a pancake flat and smooth surface with ultra-high air pressure in the tires and with the bike set into its lowest power mode. It’s not “cheating,” assuming they provide the real test data. It’s just putting their best pedaling foot forward. But in the real world, most of us won’t be riding in the same ideal conditions. So the “maximum” range that most e-bike companies quote simply aren’t realistic for most of us.
Throttle versus pedal assist range
This is another major factor affecting range. Any Europeans reading this, you poor things can ignore this section since your governments don’t believe you can be trusted with throttles. For the Americans, Canadians, Australians, and civil-disobeying Europeans still here with me, listen up.
The general rule of thumb is that throttle riding will nearly halve your range compared to pedal assist. That’s why most e-bike companies will list their maximum range based on pedal assist. When you see an e-bike listed as having a “50-mile range,” that’s almost certainly the pedal assist range. The throttle range is probably closer to 25-30 miles, depending on conditions. A true 50-mile throttle-only range would usually require having a battery of at least 1,300 Wh, or around twice the size of an average e-bike battery.
Some companies like Rad Power Bikes are pretty good about listing a range of ranges (get it?) instead of a single number. For example, they tell us that the RadRunner 3 Plus’s range is “Estimated 25-45+ miles per charge (40-72+ km)” in the specs section of the product page, though they’re still guilty of the slightly misleading “Up to 45 miles per charge” phrase in larger font on the main page.
How can you know an electric bike’s ‘real’ range?
There’s a messy, overgeneralized rule of thumb that I created to quickly judge approximate bike range. But be warned: It requires a small amount of math. Don’t worry though, you can handle it.
At 20 mph, my messy rule of thumb is 25 Wh/mi for throttle riding and 15 Wh/mi for pedal assist riding. This is for a decently powerful level – we’re not talking Eco Mode or Level 1 pedal assist here. At very low-power pedal assist where the rider does most of the work, it is possible to even achieve closer to 5 Wh/mi.
For anyone who uses a more sensical system of measurement, that means when riding at 32 km/h, you can generally expect somewhere around 15 Wh/km on throttle and 9 Wh/km on pedal assist, though it can drop as low as 3 Wh/km on really low power pedal assist.
So to use my rule of thumb, simply divide the watt-hour capacity (Wh) of the battery by my efficiency numbers and you’ll get the rough range. An e-bike like the RadRunner 3 Plus mentioned above with a 624 Wh battery should get roughly 624 Wh ÷ 25 Wh/mi = 25 miles of range on throttle-only riding. In sensical measurements, that’s 624 Wh ÷ 15 Wh/km = 41 km. That number actually aligns nicely with Rad’s published figures. Go figure.
Like I said though, this is a rough approximation. It can vary based on many factors. If you’re a heavy rider, you might even use slightly higher constants than I mentioned, such as 30 Wh/mi instead of 25 Wh/mi. Other factors like terrain and tire width make a big impact on this guesstimate system as well.
For science, I once took an e-bike with a teeny tiny 180 Wh battery on a long ride at the lowest possible power setting and with significant muscle effort on my part. I got a range of 56 miles (90 km), or close to 3 Wh/mi. It was grueling, but it showed what is possible, and how companies can get away with claiming sky-high ranges that may be possible, even if unlikely.
So sure, my generalized rule of thumb above uses fuzzy numbers. But they aren’t anywhere near as fuzzy as the ratings from most e-bike manufacturers.
In conclusion, I don’t intend to claim that there is malice on the part of most companies that market e-bikes. Their goal isn’t to mislead. They’re just caught in an unfortunate system where people want a short and pretty answer to what is under the surface actually a long and ugly question, “How far does it go on a charge?”
So until people are prepared to receive a table of data in response to that question, companies are basically forced to choose between giving an unimpressive albeit more honest range spectrum like, “It can go 20-45 miles per charge,” or to just give the rosier answer of “It can go 45 miles.” With millions of dollars on the line, you can guess which one they prefer to choose.

GM has unveiled the new version of the Chevy Bolt, its popular, affordable EV with an upgraded battery and an otherwise very similar package to its last iteration, and we’re on the scene at the unveiling at Universal Studios Hollywood to get you all the info you need.
The Chevy Bolt was originally released in the 2017 model year. It was GM’s first real, modern effort at an EV, designed to be all-electric rather than a compliance car like the old Chevy Spark EV. (GM did previously design the EV1 from the ground up, but it came along before the lithium ion era of EVs, and was decidedly a compliance car).
It was also a great car. Not only was it a good size unlike the ridiculous land yachts we’re seeing so many of today, it had a phenomenal price, especially near the end of the model’s life. It was good enough to be Electrek’s vehicle of the year for 2022.
But, due to an extended recall and because the Bolt used GM’s first-gen EV platform, rather than its whiz-bang new “Ultium” system, GM retired the vehicle in late 2023, even though it was having its best sales year ever.
But, that wasn’t the end for the model. After declaring the Bolt dead but before ending production on it, GM said that it would bring back an Ultium-based Chevy Bolt (which our publisher Seth Weintraub has taken to calling the “Boltium”).
And now, it’s finally time for the official unveiling, and we’re on hand at Universal Studios Hollywood for a “Bolt Block Party” showing off the new vehicle.
Meet the new Bolt, same as the old Bolt
When Chevy retired the Bolt and said they would bring it back later, we expected it to be similar, but perhaps not this similar. From the exterior, the new Bolt and the old Bolt EUV are nearly indistinguishable.
The front fascia is slightly modified with a black line between the headlights and no black border around the fake grille, and the rear has different taillights (lifted higher, a big demand from Bolt owners), and slightly more paint on the bumper. That’s about it. But we knew all that already, after seeing it charging in public last week.
Now we’re getting information on the interior and specs, which are the juicy updates we were hoping to hear changes on.
GM hasn’t publicized 0-60 times yet, but the Bolt will use the same motor as the Equinox EV, which gives 210hp. That’s about the same as the previous Bolt, and it weighs a similar amount, so we’re imagining similar performance as the 6-ish seconds 0-60 of the previous Bolt – peppy and more than enough for any daily needs, but not a sportscar.
In particular, the original Bolt’s main technical limitation was its low DC charge speed. It maxed out at 50kW, but often was even slower than that. In a world where many vehicles can now charge at 200kW+ speeds, the new Bolt needed an update.
Thankfully, it got one. The new Bolt is now capable of a 150kW charge rate, with a 10-80% charge in 26 minutes. GM says this is about three times faster than the previous generation.
This is due to a new 65kWh LFP battery, utilizing GM’s Ultium EV platform. The previous Bolt used LG cells, and was built before GM developed Ultium. This led the Bolt to be the only vehicle in GM’s EV stable on a different technology, and is what necessitated its retirement and retooling.
The new battery also offers different specs, with 255 miles of range (GM estimate). That’s a bit more than before, which is nice, plus you can charge to 100% every night because it’s LFP. But the DC charge speeds are really the bigger story here. Faster DC charge rates enable more seamless roadtrips.
Further enabling those roadtrips is the Bolt’s new NACS port, allowing it to use the Tesla Supercharger network. An adapter is still available to use on CCS networks, but Superchargers are typically a better experience, and the whole industry is moving in that direction at this point.
Another major change is in the Bolt’s software. The previous one had CarPlay, but this one won’t.
A lot of people are unhappy about that, and I understand the unhappiness. People have gotten used to CarPlay (or Android Auto), and lots of people love it, because it’s so much better than the software from whatever 2010s-era vehicle they came from. Infotainment systems have been horrendous in vehicles for a long time.
However, I argue that these phone-based car UIs aren’t actually that great. They are inherently generic, and unable to be tied deeply into vehicle functions in a way that provides a single coherent interface. That’s why I actually liked the UI in the Blazer EV, GM’s first implementation of its post-CarPlay solution, and continue to think that GM made an acceptable choice here.
So, I do think the Bolt UI will turn out okay. GM may take a little time to iron out some kinks, but in the longer term, I think this solution is better, and will enable over-the-air updates which saves time and trouble for everyone.
The interior has had a refresh with larger display, added ambient lighting, and cupholders which can be rearranged to accommodate larger cups. It also has more dash storage for passengers.
Rear cargo space is the same as the outgoing Bolt EUV at 16 cubic feet with the seats up, or 57 with the seats down. Incidentally, with the seats down, this is actually the same amount of cargo space as the Equinox EV, which is 20 inches longer than the Bolt. Quite a feat of packaging efficiency here.
Finally, and perhaps most importantly, the price. Chevy says the launch edition will be a limited run at $29,990, and then later will be accompanied by an LT trim with base price $28,995. That’s quite an attractive price, and as of right now, makes it the cheapest EV announced in America.
Electrek’s Take
One interesting thing about this unveiling is its timing – or rather, the timing of another unveiling which happened just about 24 hours ago. That’s when Tesla finally took the wraps off its long-promised “more affordable” EV, which turned out to just be a stripped-down version of its Model 3/Y with a still disappointingly-high $37k-$40k base price.
Tesla’s timing for that announcement could have been an attempt to steal the wind from the Bolt’s sails, but given the pricing of that vehicle compared to this one, we’re thinking that there may not be much cannibalization.
My main disappointment in the Bolt is that the new model is based on the EUV version, rather than the EV version. The previous iteration of the Bolt originally came in a smaller version dubbed the EV, with a six-inches-longer EUV version coming later. The EV actually sold in higher numbers than the EUV throughout the model’s life, but it was also available for longer.
But when Chevy announced it would bring back the Bolt, it said the new version would be EUV-only. At the time I found this folly, and I still do. We need smaller cars, not larger ones. While the EUV is still a more reasonably-sized vehicle than almost anything else on the road, I am still disappointed that it is moving in the wrong direction as far as size goes.
Nevertheless, in the current US environment where everyone seems determined to make using roads as unsafe as possible, the EUV is still smaller than the vast majority of cars available
And the price, well, that’s really the kicker. After republicans raised the price of every EV by $7,500 during an affordability crisis, with unwise tariffs also inflating consumer prices at the same time, it’s getting harder to buy a vehicle.
But the Bolt now joins the fray as one of the most affordable EVs out there, alongside the new Nissan Leaf which will cost under 30k (and even less, once a future lower-spec trim is announced), and significantly cheaper than other low-ish-priced EVs like the Equinox EV, Ioniq 5, and the aforementioned “more affordable” standard Model 3/Y.
That’s a big deal, and it makes the new Bolt a similar calculation as when it earned Electrek’s Vehicle of the Year. But now, it doesn’t even have the main downside it had at the time – its low DC charge rate, and battery questions during what was a messy recall. Both of those problems were solved here, leaving a calculation with few downsides.
We haven’t driven the car yet, though we’ll get a few minutes in it later in the event. But it’s only going to be around the block at the Universal backlot, so we can’t give a full review, but from what we’ve seen today, it looks like quite an attractive value proposition.
We’re still at the event right now for the next few hours, so if you’ve got any questions that you’d like us to check on or relay to GM employees, let us know in the comments and we’ll see if we can get some answers (especially you Bolt owners). And, we just got all this info, so we’ll be updating this article as we digest more.

New York-based Cool Down makes a thermal transfer system that moves naturally cool air from your basement into your living space while sending excess heat back down below to cool homes more efficiently. By dispersing that heat into the ground, Cool Down helps keep homes comfortable during hot summer months and cuts electricity bills in the process.
Cool Down’s system has already been shown to reduce air conditioning use by up to 67% per season by leveraging the consistent temperatures found in basements. With the release of its upgraded Smart Control Unit, the company is adding even more functionality and savings for homeowners across different climates.
The new Smart Control Unit introduces a range of intelligent features that make the system more versatile and user-friendly. Homeowners can now see their estimated energy savings in real time, giving them a clear picture of their return on investment and helping them optimize system performance. A new Basic Heating Mode means the system can now be used in winter to capture and circulate heat from areas with wood or pellet stoves, mini-splits, or rooms with south-facing windows. The addition of a Dehumidification Mode allows your AC or heat pump to dry out basement spaces just like the rest of the house, improving indoor air quality and further reducing cooling costs.
For days when comfort takes priority, Power Boost Mode temporarily ramps up cooling and dehumidification performance. Eco Boost Mode maximizes efficiency by preventing the AC or heat pump from switching on, which is ideal for shoulder seasons or mild climates. And for homes without ductwork, Standalone Mode enables Cool Down to operate as a central cooling system on its own, delivering significant cost savings even if it’s not as powerful as a traditional AC.
“The Smart Control Unit is about putting more control – and more savings – in the hands of homeowners,” said Damien Semel-DeFeo, founder of Cool Down. “These new modes allow the system to be customized for any home, climate, or energy-use goal.”
Cool Down offers a practical, low-cost alternative or supplement to traditional cooling systems as electricity rates continue to rise nationwide. The system is professionally installed in just a few hours, integrates with or without existing HVAC equipment, and requires no refrigerants, compressors, or external condensers.

The IONIQ 9 is about to get an upgrade. Hyundai’s new electric SUV was spotted with some serious off-road upgrades, hinting that a new XRT trim is on the way.
The Hyundai IONIQ 9 XRT brings a new off-road look
It may look like it’s straight out of the future, but Hyundai’s first three-row electric SUV is actually pretty impressive.
The IONIQ 9 offers a lounge-like interior with space than a Ford Explorer, boasts an impressive driving range, and features an interior loaded with advanced tech and digital screens. What else could you ask for?
How about an upgraded off-road version? We knew the IONIQ 9 was likely due for the XRT treatment after a camouflaged model was spotted last year rocking all-terrain tires, a souped-up suspension, and an added tow wrench on the front bumper.
Hyundai’s design boss, Simon Loasby, confirmed that two new IONIQ 9 variants, including a rugged off-road and a high-performance model, were in the works after unveiling the electric SUV last year.
According to TheKoreanCarBlog, Loasby said, “We are working on two distinct projects—N and XRT—apart from the standard lineup,” Loasby said.
After another IONIQ 9 with similar off-road elements, it seems only a matter of time before Hyundai makes it official.
The new photo from Kindelauto shows a prototype with similar upgrades to the vehicle spotted last year, including large all-terrain tires, a lifted suspension, and more.
A new video from HealerTV offers a closer look at the IONIQ 9 XRT in South Korea. The footage reveals unique tow hooks and an added XRT screen, which hasn’t been seen in the IONIQ lineup yet.
From the side, you can see the XRT model is slightly taller than the standard IONIQ 9 with off-road tires. Like the IONIQ 5 XRT, the larger electric SUV is expected to receive XRT-exclusive front and rear bumpers, side skirts, and 18″ wheels.
Inside, the IONIQ 5 XRT model features H-Trex seating with the XRT pattern, logo, and XRT-badged all-weather mats.
The 2026 Hyundai IONIQ 9 starts at $60,555 in the US with an EPA-estimated range of 335 miles. In Europe, the IONIQ 9 will start at £64,995 ($87,500), offering a WLTP driving range of up to 385 miles.
